ZBDC51BB可以用两节AA电池进行供电,包括一些基本外设:Serial Flash、LEDs、UART、Joystick、Buttons。
ZBDC51BB具有SoC仿真下载接口，可以用本工作室产品CC Debugger对ZBDC51RM（一款采用CC2530F256的射频模块，接口与TI CC2530EM兼容）进行仿真下载程序通过。
在ZBDC51BB上具有两个不同作用的开关：S1是电源开关。
◆S3是RM型号选择开关。
注意：RM型号选择开关应当选择到SOC/TRX当你把C51内核的SOC芯片的RF 模块插到ZBDC51BB上时，在使用本套件是选择SOC/TRX。
当你用CCMSP430-EM430F2618模块板（不含在本套件中）插到ZBDC51BB上时，RM型号选择开关应当选择到MSP。
2、产品特点●兼容SmartRF05BB电路板●具有在线下载、调试、仿真功能●开发方便、快捷、简单●灵活配置。

Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.1.FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.2.Thermal Resistance measurement obtained via infrared Scan Method.See specific marking information in the device marking column of the Electrical Characteristics table on page 3 of this data sheet.DEVICE MARKING INFORMATIONDevices listed in bold, italic are ON Semiconductor Preferred devices. Preferred devices are recommended choices for future use and best overall value.ELECTRICAL CHARACTERISTICS (T A = 25°C unlessotherwise noted, V= 0.95 V Max. @ I = 10 mA)4.Nominal Zener voltage is measured with the device junction in thermal equilibrium at T L = 30°C $1°C.5.Z ZT and Z ZK are measured by dividing the AC voltage drop across the device by the ac current applied.The specified limits are for I Z(AC) = 0.1 I Z(dc) with the AC frequency = 1 KHz.V Z , NOMINAL ZENER VOLTAGE (V)−1012345678Figure 1.
